Simulation analysis of Ruthenium-based Dye Sensitized Solar Cells

2016

Dye Sensitized Solar Cell (DSSC), usually referred as one of the most promising third generation photovoltaic devices, is an electrochemical device in which a molecule (i.e., the dye) chemisorbed onto the surface of a porous material absorbs the incident light and, thus, transfers an electron to the wide band gap semiconductor material. The injected electrons can diffuse through the semiconductor up to the collecting anode without the risk of recombination. The roles of the electrolyte which permeates the cell are to regenerate the ionized molecule and to implement a hole-transporting layer, allowing to repeat the abovementioned process. Thanks to this behaviour, semiconductors with large a…

Uno strumento virtuale per il monitoraggio e il controllo di un impianto fotovoltaico a concentrazione

2014

In questa memoria si presenta una sintesi delle attività condotte nell'ambito del progetto SERPICO ("Sviluppo E Realizzazione di Prototipi di Inverter per impianti fotovoltaici a Concentrazione", PO-FESR Sicilia 2007-2013, Misura 4.1.1.2). Il progetto ha riguardato lo sviluppo di un prototipo di impianto fotovoltaico-termico a concentrazione e del relativo sistema di monitoraggio e controllo. Tale sistema permette di acquisire le quantità sia elettriche che termiche. Inoltre esso implementa un algoritmo per l'inseguimento solare utilizzato per ottimizzare la produzione di potenza.

Luokan työrauhaan vaikuttavat tekijät : sekamallin sovellus

2017

Tämän pro gradu -tutkielman tarkoituksena oli tarkastella koululuokkien työrauhaan vaikuttavia tekijöitä. Aineistona käytettiin Niilo Mäki Instituutin Prokoulu-projektin tutkimusaineistoa. Vastemuuttujana käytettiin oppilaan arvioimaa luokan työrauhaa. Selittäviksi muuttujiksi asetettiin aiemman tutkimustiedon perusteella oppilaan arvioita erilaisista sosiaalisista suhteista ja käyttäytymiseen liittyvistä asioista, luokan opettajan ominaisuuksia ja arvioita koulun toimintakulttuurista sekä yleisiä luokkaan liittyviä ominaisuuksia. Analyysimenetelmänä käytettiin hierarkkista lineaarista regressiomallia, ts. lineaarista sekamallia, johon asetettiin oppilas-, luokka- ja koulutasot. Sekamallin …

Ontology and protocol secure for SCADA

2014

In this work, we present a semantic cyber security system and we study its semantic intelligent systems vulnerabilities, focusing on the semantic attacks. For resolving semantic problems we propose a security global solution for the new generation of SCADA systems. The proposed solution aims at protecting critical semantic SCADA processes from the effects of major failures and semantic vulnerabilities in the modern IT-SCADA network. We used a security block in the global network access point, security protocols deployed in different network (OSI) levels and security ontologies deployed in security devices. We used our mixed coordinates (ECC) cryptography solution, this is an encryption tech…
